UNITED STATES PATENT OFFICEQ FRANK S. HYA'IT, OF BROOKLYN, NEW YORK, ASSIGNOR TO BRASS GOODS MFG. 00., OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YQRK STOPPER.

Application filed April 23, 1928. Serial No. 104,008.

This invention relates to sheet metal stoppers and more particularly to that class of stoppers used for ice bags although the invention in its application is not to be so lim- 5 ited.

The principal object of the invention is the production of a stopper of the character described adapted to be screwed into a screw-threaded neck and a connection between the neck and the stopper for preventing the loss of the stopper.

A further object of the invention is the production of a stopper of the character described in which the connection between the neck and the stopper is so constructed as to permit rotation of the stopper in the neck without entanglement of the connection.

Still a further object of the invention is the production of a stopper of the character described in which the connecting means between the stopper and neck is fastened to the neck in such manner as not to interfere with thevulcanization of the mouth of an ice'bag over the neck.

The invention consists the stopper and neck and connection therebetween hereinafter more particularly described and then specified in the claims.

In the accompanying drawing illustrat- 30 ing a practical embodiment of the inven tion:

Fig.1 is a front elevation of a stopper and neck constructed in accor-dance'with the invention showing the stopper removed or unscrewed, from said neck.

Fig. 2 is a side elevation (partly in section) of the invention showing the stopper screwed. within the neck.

Fig. 3 is a plan view of the neck.

Fig. 4 is a plan view of a modified construction of the neck.

Fig. 5 is a horizontal section on the line 55 of Fig. 4.

Fig. 6 is a perspective view of a modified 5 form of connection.

Referring to the drawing:

The stopper proper comprises a hollow sheet metal screw-threaded body 1 provided with an annular outwardly and downward- 0 1y extending flange 2 to which is secured a sheet metal annular top plate-3. Preferably a rubber gasket; is removably slipped over the body as shown in Fig. 2 whereby a tight connection between the stopper and neck, to 5 be presently described, will obtain. The

hollow screw-threaded neck into which the body of the stopper is adapted to be screwed is indicated at 5. The neck is provided at its upper and lower edges with hollow heads 6 and 7 respectively which are formed by bending the edges of the metal around and onto the side wall of the neck proper as illustrated.

It is desirable that some connection be made between the neck and the stopper to prevent loss of the stopper when it is disengaged from the neck. This has heretofore been found difficult as, when the device is used in connection with an ice bag, the mouth of the bag is vulcanized 'over the neck and the upper edge of said mouth fits snugly up against the upper bead 6. In the present case I run a wire around and within the upper bead and cut away a portion of said head as indicated at 9 and then bend the wire to form a loop as indicated at 10. A clasp 11 is hooked to said loop 10 and attached to said clasp is a chain 12. The other end of said chain is attached to an eye 13 formed of a wire the inner ends of which extend through a suitable perforation in the top plate 3, and preferably centrally thereof, the inner ends of said wire being bent over into parallelism with said plate 3 and as indicated at 14 in Fig. 2. A washer 15 is preferably interposed between said ends 14 and the plate 3. This construction permits the stopper and eye 13 to rotate or be rotated relatively to each other which prevents the chain 12 from entangling when the stopper is screwed into the neck or unscrewed therefrom.

In the modification illustratedin Figs. 4 and 5 I dispense with the Wire 8 and prefer, as a. substitute therefor, to flatten the bead 6 slightly as indicated at 16 and to .provide said flattened portion with a perforation 17 through which the clasp 11 may be inserted.

In the modification shown in Fig. 6 Ihave provided a'split ring 18 of spring-like metal to which one end of the chain 12 is attached in any manner the other end thereof being secured to the stopper as in the preferred form of the invention. The ring 18 is mere- 1y snapped over the neck beneath the flange 6 and is easily removed when desired.

It will be noted that when the stopper is screwed home into the neck 5 the outwardly and downwardly extending flange 2 thereof overhangs the bead 6 and lies in proximity thereto and serves in a measure therefore to hide the connection between the chain 12 and the bead.

What I claim as my invention is 1. In a device of the character described, a neck provided with a flange terminating in a curled edge forming a hollow bead with a cutaway portion therein, a wire supported within said bead and having a part thereof exposed 11L the point of said cutaway portion, a stopper for insertion within said neck, and a flexible retaining element rotat ably connected to said stopper and attached to the exposed portion of said wire.

22. In a (lOVlCO of the character described,

a neck, a reinforcing bead on said neck, a hollow stopper adapted to interfit with and close said neck and provided with a downwardly and outwardly overhanging flange extending outwardly over said head and 1 ing in proximity thereto when the stopper is in closed position and means rotatably connected to said stopper and extending through the upper wall thereotandattached to said head for preventing loss of Said stopper.

Signed at Brooklyn in the countyofKings and State of New York this 21st day of April A. D. 1926.
